Writers should first focus on his core traits. Rin is brave, so in any crossover, he should face challenges head - on. For example, if it's a crossover with a magical girl universe, he'd be the one jumping into danger to protect others. His loyalty to his friends and family is also important. In a crossover with a post - apocalyptic world, he'd do anything to keep his loved ones safe. Also, his hot - headedness should be there. If he's in a high - society crossover, he might get into arguments with the snobby characters because of his quick temper.
The characters would likely be initially cautious. For example, Yu from Persona 4 might be a bit reserved when meeting Joker from Persona 5, but as they learn about each other's goals, they would start to trust. Yosuke might be excited to see the more high - tech Metaverse compared to the TV World, and he could bond with Ryuji over their shared love for adventure. Chie would probably challenge Ann to a fight at first, thinking she's just a pretty face, but then realize Ann's strength.
